This Week's Guests:

• It seems like everyone can be a photographer today, but are you really thinking before you snap that photo? National Geographic photographer Joel Sartore visits the studio to chat with Boyd about his new book, Photographing Your Family. Sartore explains what you need to think about to take a great everyday photo.

• Have you ever dreamed of being a National Geographic travel writer? Suzanne Roberts did and her dream is about to become reality. As the winner of the National Geographic and Travcoa Next Great Travel Writer Contest, Roberts will travel to Mongolia and the Gobi Desert then write about her trip for the National Geographic Traveler website.

• Photographer, Vincent Musi is a frequent contributor to National Geographic magazine. This month he shot portraits of dolphins, orangutans, fish and elephants for the article "Inside Animal Minds." Boyd and Musi talk about cognitive research in animals and the conversations Musi had with his quite intelligent subjects.

• Dave Wiley is a research coordinator for the Stellwagen Bank National Marine Sanctuary. He and his colleagues are traffic controllers between whales and ships in the waters off of Boston. Dave chats with Boyd about how NOAA and shipping companies are minimizing collisions between tankers and whales by re-routing the shipping lanes.
